Katy Perry has announced details of her new single - you can listen to it below.
The track, entitled 'Part Of Me', is taken from upcoming repackaged album Teenage Dream: The Complete Confection.
The single will be released on February 21, followed by the album on March 26.
Speaking about her updated collection, Perry said: "This is the complete story of Teenage Dream.
"It was an incredible honour to tie the King of Pop's Billboard Hot 100 record, but I'm moving forward and had a few things left to get off my chest. So this is the complete special edition of my album for my fans."
Katy Perry joined the likes of Rihanna, Coldplay, Nicki Minaj and Lady Gaga at last night's Grammy Awards.
